حَدَّثَنَا يَحْيَى بْنُ إِسْحَاقَ أَخْبَرَنَا ابْنُ لَهِيعَةَ عَنِ أَبِي الزُّبَيْرِ عَنْ طَاوُسٍ قَالَ رَأَيْتُ ابْنَ عَبَّاسٍ يَجْثُو عَلَى صُدُورِ قَدَمَيْهِ فَقُلْتُ هَذَا يَزْعُمُ النَّاسُ أَنَّهُ مِنْ الْجَفَاءِ قَالَ هُوَ سُنَّةُ نَبِيِّكَ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ

It was narrated that Tawoos said: I saw Tbn 'Abbas (PBUH) sitting on the balls of his feet (when his feet were spread out) and I said: The people claim that this is difficult. He said: It is the Summit of your Prophet (PBUH).
